Coffee Bean Roasting: Categories and Techniques

Coffee bean roasting classification

Coffee bean roasting is an important step in making coffee with a strong aroma and rich taste. Coffee beans can be classified into different categories according to the degree of roasting and origin. Here are some common classification methods.

1. Roasting degree

According to the degree of roasting, coffee beans can be divided into three categories: light roasted, medium roasted and dark roasted.

- Light roasting: Light roasting means that the coffee beans are lightly processed at a lower temperature to retain the original flavor and acidity. This method is suitable for high-quality coffee beans from some special origins or varieties.

- Medium-fried: Medium-fried means that the coffee beans are processed at an appropriate temperature, so that their surface turns dark brown and has a balanced sweet and sour taste. This is the most common and popular category.

- Dark Brown: Deep brown means longer time and higher temperature processing, making the surface of the coffee beans very black and more roasted. The coffee produced by this method usually has a strong bitter taste and burnt aroma.

2. Origin

Depending on their origin, coffee beans can be classified into different types, such as Arabica, Robusta, etc.

- Arabica: Arabica is the most popular and widely used type of coffee beans. They usually have higher acidity, floral aroma and smooth taste.

- Robusta: Robusta is another common coffee variety. Compared to Arabica, Robusta is easier to cultivate and has a stronger and more bitter taste.

3. Tips and precautions

No matter which classification method you choose for baking, the following tips should be noted:

- Control the temperature: Different degrees of baking require different temperature ranges. Too high or too low will affect the final taste.

- Roasting time: Roasting time is also an important factor affecting the taste of coffee. Too long or too short a time will lead to unsatisfactory results.

- Cooling: After roasting, the coffee beans need to be properly cooled to prevent further heating and excessive oxidation.

- Storage conditions: To maintain the freshness and taste of coffee beans, they should be stored in a dry, dark and airtight container.
